not cause the output voltage to go outside the specified voltage unbalance or phase
displacement.

interface cable with a 25-pin subminiature D-shell connector to fit the serial port of the computer
file server. Cable shall be available in selected lengths from 25 to 300 feet.
O. Optional Multi-Computer Interface System
A Multi-Computer Interface System shall be provided where a single UPS is powering multiple
computer file servers (up to 48). This system shall perform an automatic unattended orderly
shutdown of the customer뭩 operating system in each computer when necessary. The MultiInterface Unit (MIU) shall provide the hardware required to interface the UPS to each computer.
The software provided allows each computer to monitor the UPS for power failure and low
battery alarm while operating as a background task. After a power failure occurs, the software
shall perform an automatic shutdown of each computer when the pre-programmed timer
expires. If the UPS reaches a low battery alarm, the software shall override the timer and
perform an automatic shutdown of each computer. This system requires the optional remote
contact board to provide isolated normally closed contacts. This system shall include a shielded
primary cable with a 9-pin subminiature D-shell connector, the Multi-Interface Unit (MIU), and
shielded secondary cables with RJ11 and 25-pin subminiature D-shell connectors. Cables shall
be available in selected lengths from 25 to 300 feet.
P. Optional IBM* AS/400* Multi-Interface System
An AS/400 Multi-Interface System shall be provided where a single UPS is powering multiple
AS/400 units (up to 8). The MultiInterface Unit (MIU) shall provide the required UPS status
information to each AS/400 so it can perform an automatic unattended orderly shutdown when
necessary. Each AS/400 includes the software required to interface with the UPS. The following
status messages are activated in the IBM system:
•
•
•
•
UPS on (UPS is supplying power)
Bypass active (bypass is supplying power)
Utility failure (battery is discharging)
Battery low (limited battery time remaining)
Each AS/400 individually monitors the UPS status to determine when to initiate a quick power
down to preserve data and protect hardware during a utility power outage. This system requires
the optional remote contact board to provide isolated contacts. This system shall include a
shielded primary cable with a 9-pin subminiature D-shell connector, the AS/400 Multi-Interface

Unit (MIU), and shielded secondary cables with RJ11 and 9-pin subminiature D-shell
connectors. Cables shall be available in selected lengths from 25 to 300 feet.

Q. Optional Internal Modem
The UPS shall come with an internal modem capable of dialing out from the UPS to notify up to
two remote computers, terminals, PC뭩, or pocket pagers when important events occur. The
modem will also be capable of accepting incoming calls, with the appropriate security, and
connecting to a remote terminal, computer or PC, to perform all those functions normally
available on the front panel including viewing monitoring screens, turning the UPS on and off
and setting modifiable values.
R. Optional SNMP
The UPS shall come equipped with an internal SNMP adapter, which will connect the UPS
directly to any I.P. based network using either Ethernet or Token Ring communications. The
UPS will become a managed device on the network. From a network management station the
system administrator shall be capable of monitoring important system measurements, alarm
status and alarm history data. The network administrator shall also be capable of executing
battery tests, observing the results of such tests and turning the UPS on and off via his SNMP
communications network. In the event of a utility failure the SNMP shall continue with live
communication without the requirement of additional or separate UPS equipment until such time
as the UPS shuts down for Low battery. On resumption of Utility power the SNMP shall resume
full SNMP communication automatically.

MANUFACTURER뭆FIELD SERVICE
3.2.1 Service Personnel
The UPS manufacturer shall directly employ a nationwide service organization, consisting of
factory trained field service personnel dedicated to the start-up, maintenance, and repair of UPS
and power equipment. The organization shall consist of regional and local offices.
The manufacturer shall provide a fully automated national dispatch center to coordinate field
service personnel schedules. One toll-free number shall reach a qualified support person 24
hours/day, 7 days/week, 365 days/year. If emergency service is required, response time shall
be 20 minutes or less.
An automated procedure shall be in place to insure that the manufacturer is dedicating the
appropriate technical support resources to match escalating customer needs.
3.2.2 Replacement Parts Stocking
Parts shall be available through an extensive network to ensure around-the-clock parts
availability throughout the country.
Recommended spare parts shall be fully stocked by local field service personnel with back-up
available from national parts center and the manufacturing location. The national parts center
Customer Support Parts Coordinators shall be on-call 24 hours a day, 7 days a week, 365 days
a year for immediate parts availability. Parts from the national parts center shall be shipped
within 4 hours on the next available flight out and delivered to the customer뭩 site within 24
hours.
3.2.3 UPS Maintenance Training
Maintenance training courses for customer employees shall be available by the UPS
manufacturer. This training is in addition to the basic operator training conducted as a part of
the system start-up.
The training course shall cover UPS theory, location of subassemblies, safety, battery
considerations and UPS operational procedures. The course shall include AC to DC conversion
and DC to AC inversion techniques as well as control, metering, and feedback circuits to the
Printed Circuit Board (PCB) level. Troubleshooting and fault isolation using alarm information
and internal self-diagnostics should be stressed.
3.2.4 Maintenance Contracts
A complete offering of preventive and full service maintenance contracts for both the UPS
system and battery system shall be available. An extended warranty and preventive
maintenance package shall be available. Warranty and preventive maintenance service shall be
